555 driver hangs on booting 6.5.0-45-generic kernel

Ok here is the important information I was able to identify from your posts…

Linux Kernel: 6.5.0-45-generic x86_64

Distro: Ubuntu 22.04.4 LTS (Jammy Jellyfish)

Desktop: GNOME 42.9

Display: x11 server

Graphics:
Device-1: Intel Alder Lake-P Integrated Graphics driver: i915 v: kernel
Device-2: NVIDIA GA106M [GeForce RTX 3060 Mobile / Max-Q] driver: nouveau
v: kernel

The problem: hang on boot

It happens after system update and reverting doesn’t fix it.

And, you say that secureboot is disabled, and that is what would require your kernel modules to be signed, otherwise it is normal if they are not.

So, it appears to me, that updates broke your system…which is a common problem.

The error messages you posted are normal(which means they can be ignored), until your next post,
where you found…

EE) Failed to load module "nvidia" (module does not exist, 0)

Jammy Jellyfish is the super stable ubuntu right now, with the most resources available to it, so it’s the ideal system, but it’s also so old, that there are issues with using it, that don’t get fixed, since development is focused on newer versions of ubuntu. That means, we the users, have to do a little manual labor sometimes, which isn’t so bad…

Please add how you installed your system, and how you attempted to install the NVIDIA driver the last time you attempted to install it.

And I would recommend using the Nvidia.run tool to attempt to fix your problem, which has a lot of neat features built into it, presents you with the latest driver, the latest libraries, which will integrate with your system well…

All graphics/gaming related stuff should be updated to the latest versions from their resources directly ideally to begin with, and distributions don’t automate that for us.

The only thing that sucks about ubuntu is that the grub menu isn’t active by default if my memory is correct, which makes doing low level stuff like installing the Nvidia driver easier.

In this post I describe the way I install it, but there are other ways.

Please pay attention to the installers instructions, and attempt to correctly install the driver as I outline in the post. The Nvidia.run file will actually uninstall your old driver, and then, reinstall it correctly.

Also you have two graphics cards on your system, identify in your computer’s BIOS which graphics card is set to be your primary graphics card, to make sure you are actually using nvidia, and later maybe you can set up prime if you’re feeling adventurous
